BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to a children balancing vehicle, and moreparticularly to a children balancing vehicle having simple structure andcapable of being conveniently assembled.

2. Description of the Related Art

According to current children bicycles, auxiliary wheels are requiredand mounted at two sides of the bicycle rear wheel. However, whenchildren are in learning stage of riding these bicycles, they are unableto perform two motions of handle control and stepping on pedals of thebicycles. Children usually use feet to rub against ground for advancing,and the motion may harm the feet while colliding the pedals. Inaddition, because auxiliary wheels are mounted at two sides of the rearwheels of the bicycles, children may excessively rely on the auxiliarywheels during bicycle riding, incapable of quickly learning the balanceof riding bicycles, resulting in prolonging time of learning. Further,while relying upon auxiliary wheels, the oblique angle between theauxiliary wheels and the vehicle bodies may be gradually increased tobring about danger of overturn during riding. A balance bike capable oftraining equilibratory sense of infants then is developed in market.

A conventional balance bike is to dispose a front fork at a front sideof the vehicle rack. A top end and a bottom end of the front fork arecombined with a steering head and a front wheel, and a rear wheel isdisposed at a rear end of the vehicle rack. By comparing with aconventional bicycle, the balance bike does not have transmissionstructures of pedals, tooth discs and chains. When an infant rides thebalance bike, the counter-reaction force generated by feet of the infantstepping on ground drives the balance bike to slide forward at inertiaforce so that the infant can be familiar with the motion of thetwo-wheel vehicle to train the equilibratory sense and coordination ofthe brain of the infant. Therefore, when the infant rides a conventionalbicycle, he/she may have equilibratory sense and confidence to easilyride the bicycle. However, the structure of the conventional balancebike is more complicated, and the assembling is not convenient.Moreover, in the structure of some balance bike, its vehicle rack isintegrated and unable to be detached and assembled, resulting ininconvenience.

SUMMARY OF THE INVENTION

Therefore, upon the foregoing problems, it is a primary objective of thepresent invention to provide a children balancing vehicle having simplestructure and capable of conveniently assembled.

To achieve the foregoing objective, the children balancing vehicle ofthe invention comprises a front vehicle rack, a handle set, a rear fork,a seat tube and a fastening component. The front vehicle rack has afront fork. A front wheel is assembled below the front fork while astand pipe is disposed thereon. A vehicle rack body is disposed at arear of the stand pipe. The handle set is disposed onto the stand pipe.The rear fork has a plastic main body. A rear wheel is disposed belowthe rear fork. The seat tube passes between the vehicle rack body andthe plastic main body of the rear fork. A seat cushion is disposed ontothe seat tube. The fastening component passes among the vehicle rackbody, the plastic main body of the rear fork and the seat tube so as tomutually assemble and fasten them. An assembling of the whole childrenbalancing vehicle can be composed by using simple fastening components.The children balancing vehicle can allow children to be familiar withthe motion of two-wheel vehicles, thereby training the balance andcoordination of brains of children.

An assembling of the whole children balancing vehicle can be composed byusing simple fastening components. The children balancing vehicle canenable children to be familiar with the motion of two-wheel vehicles,thereby training the balance and coordination of brains of children.After children learn how to balance and control bicycles, the inventioncan become a mode of normal bicycle by replacing the rear fork having apedal set through the fastening component so that children learn themotion of the pedals. Since difficult balance and control have beenlearned, the forward motion can be quickly learned by cooperating withthe pedals so as to reduce time of riding the vehicle.
